While I do not belong to any religion, your series reminds me of a couple of pieces of mine. My essay, https://medium.com/know-thyself-heal-thyself/how-do-you-define-god-9898492eae9, starts with a four stanza poem, of which this is the first:

"God

So many ask

Why do you allow suffering?

Why should we believe that you exist?

Child, why must I prove existence to you?"

and then there is my https://medium.com/illumination-curated/love-letters-to-god-79268db5dc45, which contains these lines:

"God

I write thee love letters every day

With all my soul cried despite my ego

God

Regardless of what atheists profess from darkness

We both know you exist without proof thereof

Hashem"
